T all 107mm it may concern Be it known that I, Haavnr OLIVER WIT- wrui.a subject of the King of (treat Britain, and a resident of New Hamburg,Ontario, Dominion of Canada, have invented a new and Improved T i'ainlipe Coupling, of which the following is a full, clear, and exactdescription.

The invention relates to train pipe couplings for conducting air,stcani, electricity and other fluids from one part to another forbraking, signalin heating and other purposes.

The object of the invention is to provide a new and improved automatictrain pipe coupling, arranged to insure an automatic coupling of thetrain pipes of two cars cou iug together, to cut ott' the fluid pressurein the train pipes on the cars being uncoupled, to cause an emergencyapplication of the iluid prcssure brakes in case the cars accidentallybreak apart, and to provide electrical connection between adjacent carsfor a return circuit telephone and electrical signaling system and forelectric power trans mission, either hghting or motive power.

For the purpose mentioned, use is made of a coupling head attached to acoupling pipe moving bodily with the draw bar, and having movementindependent of the draw bar in both a longitudinal and lateraldirection, the coupling pipe being provided with a: valve controlledbythe movement of the coupling, pipe and its head.

A practical embodiment of the invention is represented in theaccompanying draw-, lugs forming a. partof this specification, in whichsimilar characters of reference indicatov corresponding parts in all theviews.

I The cars A, A are providedat their ends with fluid pressure coupling, members B, B, inounted onsupports or hangers C, C, depcnding from and moving bodily with the drawbars D, D, mounted to, slide in the usualmanncr on the cars A, A, andprovided with coupling members F1. E, of any approved type. The couplingmember,- B, ll are alike in coustriurtion, and hence it sulliccs todescribe but one in detail. A cou plinp: pipe l terminates at its foranal end in a cloupliup hen d (i, in the rear of which is located avalve ll connected by a hose 1 with the. train pipe J, extending underthe car A (A) in the usual manner, and provided with an angle cock Jnormally open. The pipe F is mounted to slide in the direction of itslength in a bearingv K, provided on its, 100 sides with trunnions K.(see Fig. l). exlendins, in elongated slots C formed in the side of thesupport or hanger (l,-so that the boaring K can swing up and down andwith it the pipe F, and the bearing K can also turn 105 in alateraldirection owing to the elongation of the slot 0', as will be rcadi yunderstood by reference to Fig. 1. The coupling pipe F and itscoi plinghead G are normally held in a forward position by the action of spring,110

mg 0 formed in a slide devices L, head F, closing the rear end of thecorresponding coupling pipe F, and the said spring devices L, L areconnected at their forward ends to the support or hanger C, the springdevice L extending upwardlv and forwardly from the head F to the supportC, while the spring device L extends forwardly and downwardly from thehead F to the support C. Each spring device L, L consists of a spring Lressed on at the ends by collars L l held on the rods L, l),evtendinpthrough the springs L in 0p-- posite.directions, to connectwith the head I and the support C, respectively, as will be readilyunderstood 1) reference to Figs. 1 and The rear rots L of the spring:devices L, L are preferably in the form of links having a slidingengagement with the head F.

The spring devices L, L operate in conjunction with a bar F and a pin Cto hold the pipe F in the angular position shown in Fig. 11, that is,holding the pipe in a horizontal plane at an angle to the longitudinalcenter line of the car. The bar F is secured at its forward end to therear end of the head G, and the said bar F is secured at its rear end tothe valve H, and is provided between its ends with a lengthwiseextendingslot F into which projects the pin C extending transversely from thebrace C forming part of the support (I. hen the cars are uncoupled thepin C is at the rear end of the slot F and the spring devices L, L areunder sufiicient tension to pull the pipe F to an angular po sition, thetrunnions K of the bearing K permitting such movement of the hearing Kand its pipe F. The angular position of the pipe F in a transversedirection moves the coupling head Ginto what I prefer to call secondaryangle of approach, as indicated in Fig. 11. The bar F also serves as aguide to prevent the pipe F and the head G from revolving.

The valve H is provided with a valve plug It for connecting the hose Iwith the pipe .1 or disconnecting the same, and on one outer end of thevalve plug H is secured an arm H connected with a valve-operatin5, rod Hterminatingin a head H, and having a cut-out portion H adjacent to thesaid head, as will be readily understood by reterence to Figs. 5, 6 and7. The rod ll is mounted to slide lengthwise in a bearing N formed in abracket N attached to the support C, and it also passes through an open-O, mounted to slide transversely in the bracket N and the support C, asplainly indicated in Figs. 5, 6 and 7. The slide 0 is provided at theopening 0 with a beveled portion for en gagement with the cut-outportion H in the valve-operating rod H (see Fig. 6). The

L, connected at their ends to a inner end of the slide 0 projects'into acas- -ing I, attached to the support 0, and the said inner end of theslide is pressed on by a spring held in the casing P and serving tonormally hold the slide 0 in an innermost position, as shown in Fig. 5.The inner end of the slide 0 terminates in a fork 0 provided with lugs 00, adapted to beengaged by projections Q, Q held on a tumbler or spoolQ, mounted to turn in the casing P, the said spool Q. being pressed onby a torsion spring ,f, one end of which is secured to the casinp P andthe other to the ieriphcral face of the spool Q. The spool 1 is providedwith a central opening" formed of two converging parts Q", Q, united attheir apcxes, and. through this opening extends the polygonal portion Rof a. rod R, provided with a cylindrical coupling head R engaging abearing- G formed in the coupling; head G, as plainly indicated in Fig.2; The coupling head I is round and is preferably in the form of a fork,the members of which are adapted to engage the corresponding" members ofthe coupling hcad R in the other coupling head G at the time the cars Aand A are coupled together, as indicated in Fig. 2. It is understoodthat when this takes place the cou pling heads R interlock with eachother, so that when one rod R is turned it turns the other red with itin the same direction.

The rod R is provided adjacent'to the coupling head G with atransversely-extendingr arm R provided at its free end with a pin R.engaging a slot S formed in an upright link S attached on the lower end,of a chain S connected at its upper end with a cable S mounted to slidein a bearing (3 forming part of the support C near the upper endthereof. as plainly indicated in Figs. 1, 2 and 4-. The upper end of thecable S is connected with a manipulating device E for the coupling 1*],so that the rods R are turned on uncoupling the couplings I) whenactuating the device 'E. Now when the rods R are turned the tumblers Q,are turned with the rods to cause the projection Q or Q to act on thecorresponding lllf or t). with a view to shift the slide 0 m atransverse direction from the normal position shown in Fig. 5 to theposition shown in Fig. 6, to engage the projection with the cut-outportion IT in the valve-opcratingr rod H Now when the cars A, A. apartthe rods H are held locked by the slides O, and consequently move withthe supports C, while the bearings K allow the pipes F to slide therein,so that the coupling heads G remain coupled and at the same time theoperating rods H impart a swing ing motion to the arms H to move thevalve plugs H into a closed position, thereby breaking comn'iunicationbetween the hose land the pipe F. The outer end of each rod It isprovided with a nut It and on the rod R are arranged coil springs R. Rof which the spring R is intermediate the front cover I of the casing Pand the arm R while the spring R abuts against the rear cover P of thecasing P and is adapted to be engaged by the nut R to cushion the rod Rin its lengthwise movement.

The slide'() is provided at its under side with a cut-out portionadapted to be engaged by a catch T, mounted to slide in the casing 1(see Fig. 8), and having a stem T terminating in an enlarged head T,projecting beyond the rear of the casing 1, to abut against the valveII, so as to move the catch 'l out of engagement with the notch A springT is coiled on the stem '1" and presses against the head T to normallyhold the catch T in engagement with the notch and the spring T ispressed when the outer end of the head T is pressed inward on moving inengagement with the valve H. \Vhen this takes place the catch '1releases the slide 0, so as to allow the latter to return to its normalposition by the action of the spring 0. the spring Q then returning thetumbler Q likewise to its normal position. The coupling head G is preferably in the form of a diamond, as indicated in the drawings, theforward half portion forming a shoe G while the rear end is providedwith a pocket G and the rear halt portion is )rovided on the face of thecoupler head wit guides G, G, extending along the top and bottom marginsof the rear portion of the head. The forward end of the pocket (1: iscurved outwardly, so as to permit convenient entrance of the shoe G' ofthe opposing coupling head when the cars A, A are coupled together, itbeing understood that when this takes place the top and bottom edges ofthe entering shoe are guided in position and engage the guides G, G, soas to insure a firm contact between the faces of the two coupling headsG of opposing cars, and whereby the coupling heads are centered, that.is, the coupling pipes F are moved into register with each other andlike wise the bearings G containing the coupling members It. The pocketsG of the coupling heads G are preferably provided with holes (1 for theescape of snow or other extraneous matter that may pass into the pocketsG. The coupling head G is provided with a gasket G in the entranceopening for the pipe F, and this gasket G is preferably of rubberandprojects beyond the :Face of the coupling head G. The top and bottom ofthe con )ling head G are provided with 'guideways I for the reception ofpairs of contacts V for making electrical connections between adjacentcars for return circuit telephone and electric signaling systems and forelectric power transmissions &

for lighting or motive power, etc. Each metallic contact V is held in aplunger V (see Fig. of insulating material, and mounted to slide in thecorresponding guideway U and pressed on by a sprin V", to normallyproject the rounded 01F head of the contact beyond the front face of thecoupling head G when the latter is in uncoupled position. The rear endof the contact V and plunger V is provided with a binding post V for theattachment of the insulated conductor V supported by the coupling head(i and the support C (see Fig. 1), and extending to the correspondingcar A or A.

The contact V above described is preterably for use in transmittingelectrical energy for telephone signaling purposes and the like. and isarranged at the bottom of the coupling head. but for power tranrnnissionthe construction shown in Figs. 17 and if) is preferred. In this case acontact of large area is provided at the top of the coupling head G bythe use of an insulated fixed contact V projecting beyond the. face ofthe coupling head, and a yielding insulated contact V, arranged with arecess in the coupling head adjacent to the fixed contact V", the rearends of the contacts V and V being connected with the circuit wires Vand V", respectively. It is understood that the yielding or springcontact V of one coupling head G is adapted to receive the projectingend of the contact V of the opposite cou ling head G. By thearrangement. descri ed a large contact surface is provided and thereforeotters less resistance. and a sliding contact is provided to insure abetter contact than with the contacts V. the contacts V and V tending toclean one the other. It is understood that the projecting contacts V 5are perfectly guarded from in jury during coupling. owing to the shoebringing the contacts suiiiciently in line before they engagethemselves.

In order to make provision for air signaling purposes and transmissionof steam from one car to another (passenger cars mainly) use. is made ofan airsignaling aper ture X and a steam aperture Y (see Figs. 16 and 17)formed in the coupling head above and below the central apertureconnected with the pipe F. The apertures X and Y are provided withsuitable gaskets X and Y at the face of the coupling head G. and therear ends of the said apertures are connected with suitable conductingpipes (not shown), extending under the cars, for the air and steamrespectively. In order to prevent undue heating of the gaskets i andadjacent parts by the steam passing through the aperture Y, use is madeof an air space Z intermediate the aperture Y and the central openingfor the pipe F. In order to prevent the gaskets G, X and Y from age.

being damaged on coupling two heads G, the shoe G is provided on itsinner face with a raised portion or shoulder G (see Fig. 18) so that thecentral parts of the-coupling heads are held out of contact until theshoes G are nearly seated in the pockets G The shoe portion of thecoupling head G is beveled at. top and bottom to prevent adherence ofdust or other extraneous matter.

The operation is as follows: When the cars A and A are uncoupled andapproach each other for coupling, then the heads G stand in an angularposition, as indicated in Fig. 11, and. when the shoes G of the twocoupling heads G engage each other they press the heads laterally so asto finally bring the pipes F in alineinent and in register with eachother as soon as the heads (t are firmly coupled together, that is. theshoes G have passed into the pockets G. Suitable rubber gaskets may bearranged at the faces of the coupling heads G at the entrance ends tothe pipes l so as to prevent leak- Now, as the cars move farthertogether, the pipes F slide in their bearings K in opposite directions,so that the spring devices L. L for each coupling member B, B are placedunder hard tension and consequently the faces of the coupling heads Gare firmly pressed together and are held pressed together under thetension of the.

said spring devices L, L. hen the heads G of the two coupling members l3and B are coupled together, the heads R of the rods R are likewisecoupled together, and when the cars A and A move to final couplingposition, it is evident that. the supports C move toward each other andconsetpiently the heads ll of the rods H" are carried along, whereby therods ll are'shifted to turn the valve plugs ll into the open positionshown in Fig. 2. to connect the train pipes .T of the adjacent cars Aand A with each other, and thus allow fluid pressure to pass from thetrain pipe of one car to the train pipe of the other car. It will alsobe noticed that when the heads G of the two coupling members 13 and liare coupled together, the contact devices V in the two coupling headsare movcd in firm contact with each other, so as to establish electricalconnection between the two cars.

It is understood that when the cars A and A are uncoupled the valves Hare closed, and when the cars are moving into coupling engagement, thecoupling heads G, G are coupled together prior to the couplingof thedraw heads D, D, so that the spring devices L, L are placed under heavytension when the cars are finally coupled together; and it will also benoticed that on the final conpiiig movement of I supports 0, by themechanism shown in Figs. 5, 6 and 7, cause lengthwise movement of therods ll", to move the valves H into the draw heads D, D the openposition with a view to connect the train pipes J, J of the cars A, Awith each other. When therars are uncoupled and move apart, with thelink S raised and the arms R swung upward to turn the rods R, aspreviously explained, then the valves H are closed to prevent the fluidpressure from passing out of the train pipes into the atmosphere by wayof the now disconnected pipes F. It is understood that owing to thearrangementdescribed, the rods H are held against movement during thetime the heads G separate, so that the valves H are turned into closedposition, and as the spring devices L, L relax during the uncoupling,the catch T is released from the. slide to unlock the latter and allowthe same to return to normal position, thus allowing the rods H to morein unison with the pipes l ln case the cars A. A break accidentallyapartand the rods H are not locked by the slides 0, then the rods ll.more with the pipes F and hence the valves ll remain open after theheads (i, G are disengaged, to allow air to escape from the train pipeJ, with a view to apply the brakes for an eii'iergency stop. In case itis necessary to open the draw head on an uncoupled car, the operatingdevice 1') is manipulated, and the rod R and its coupling head ll isturned, but as the catch T is held withdrawn from the slide 0, thelatter is not locked and hence the parts re turn to normal position, asshown in Fig. 5, as soon as the operating device E is returned to normalposition.

ly constructing the spring devices L, L in the manner described, theyare not liable to be strained. and they tend to hold the coupling pipesF in horizontal position at the time the cars are uncoupled. and thespring devices readily yield to allow proper couling of the couplingheads G even should the same stand at different heights, as the pipes Fcan swing up or down to compensate For any discrepancy.

The construction of the coupling heads G insures positive coupling ofthe same, witliout danger of lea kage. ot' the fluid pressure, as thecontacting faces are interlocked, that is, the shoe oit' onc licadengages the pocket of the other head. It will also be seen that alljars, jolts and stresses are readily taken up by the spring devices L,L, thus relieving the coupling heads G of undue. strains.

By the co-action of the spring devices L, L, the bar F and pin C and theforward edge of the valve H abutting up against the hanger (13, thecoupling pipe F and its coupling head G are held at an angle ofapproacli (see Fig. 11), so that the forward end of the shoe of one headGstrikes the other head at about the middle when the heads cometogether, and when the cars are uncoupled the shoes readily disengagetheir interlocking pockets owing to the, sidewisc pressure exerted onthe pipe F by the action of the spring devices ll. 1/ operating inconjunction with the bar i and the pin C".

ly locating the revolvingcoupling head it" within the coupling head (i,it is completely protected and takes up little room, and by theconstruction described the action oi the coupling head ti is inde)endeut of the valve-operating rod l'l". \Vhen the shoes (i ol' thecoupling heads ti come together in the action of coupling and are forcedback against the tension of the spring devices L, It, then the springsll are com-- pressed. thus holding the coupling heads It in lirniengagement with each other. When the cars A and A separate. the springdevi es L, L force the coupling-heads ti, G outward and then the nuts11* move into ongagementwith the springs It sutticiently early in themovement. so that while the coupling heads (1: continue to the fullextent of their movement, the coupling heads R are drawn inward into ther bearings ml by the action of the said springs R and hence the couplingheads it" are disengaged one from the other prior to the time of theseparation of the coupling heads G t From the foregoing, it will be seenthat the springs ll". R" cushion. the lengthwise movement of thecoupling heads ll.

The supports er hangers may he of any approved ctmstruotion. but arepreferably in the form of links hung at their upper ends on a bracket (1attached to or forming part at the coupling members B, and the bracespreviously mentioned. are connected by links C with the brackets U", atthe junction of the supports 0 with the said bracket. The top of thelink C is provided with a. notched plate 'W, engaged by a col-resondingly-shapcd Cross bar VV', hung on lints V from the draw bar D. asplainly indicated in. Fig. 1. By the arrangement descrilard. the crossbar \V adjustahly engages the plate \V. so as to permit of properlyadjusting the support or hanger (l according to the construction of thecar on which the device is applied,

it is understood that by the arrangement described the, coupler is heldfirmly in a true alinementposition both laterally and vertically. Itwill also he. noticed that the. diverging of the spring devices Lprovides vertical components whereby the said devices; can resistunbalanced forces in a vertical plane within the limits of theirstrength. The triangularty-arranged memhers C and If. L form a yieldingtruss (i. e. non-rigidl and when the. coupler is in uncoupled position.this truss holds the pipe line in a horizontal position. The wcightot'the yieldingly mounted parts of the coupler are supported by the bearingK located in the .t'rame tending to tilt the pipe line from thehonzontal is resisted by. the vertical components ot' the springs L", U,thereby holdingthe pipe line in a horizontal position when uncouple-(1..

'lhc coupler head, althoughpreferably ol': diamoml shape would operateequally well it' of oral or elliptical shape, and since the sameprinciples-are. involved, the coupler head design is not necessarilyconfined to the limits of diamond shape but includes any geometricalfigure so long as the coupler head presents a shoe 'and a pocket. Theshoe is formed by the forward part of the coupler head and thepocket atthe rear of the coupler head is formed by guides so shaped that theytend to engage the shoe of an approaching coupler head and direct theapproaching shoe to ultimate register and firm seating in the pocket, asis the case in the diamond shaped design illustrated.
